Samsung Galaxy Note 3 GPS Issue

Anyone else having issues with their Note 3 GPS? I'm having an issue were every time I plug or unplug the charger from my phone the GPS drops out. I have to then toggle the GPS on/off in my quick settings to get it working again while navigating. It also seems to drop the signal when I get an incoming phone call while using the navigation app. I have confirmed this same behavior on 2 other friends Note 3's. I'm hoping this is just a software issue that will be fixed in a future os update.

Re: Samsung Galaxy Note 3 GPS Issue

@goldendrag0n I agree, the more I have looked at this (and my info below about the 0.75A charger) I agree that it is most likely a combonation of MJ5 update and some falty hardware. It may be as simple as, the failure is happening to the motherboard (becasue of the charger issues) but can take time depending on how bad the failure/defect is. Well my 4th phone arrives tomorrow, I'll report back when I get it, test it and load all my apps back on to test again.


Another thing to add to the oddness of this, I just tested my charger at work (It is an iGo 0.75A wasll chager) and it does NOT cause the GPS to disconnect. Just for S&G I went out to my car, and tried the 1.0A and 2.1A ports on my car charger and both of them casue the GPS to disconnect. No idea what this means or why the low powered 0.75A charger does not cause this problem, just wanted to add this bit of info...

Re: Samsung Galaxy Note 3 GPS Issue

@james27007 That's very interesting. I was using AndroTS GPS Test and when I plug in my wall charger that came with the phone, evey plug/unplug it would show the GPS chip going from ON to OFF. Then I borrowed my mom's Rugby II charger, which is a 0.7A charger, plugging/unplugging still makes me lose fix, GPS icon still goes away in notification bar and it goes to OFF too. And the charger in my car is 1.0A, so I've tested it on 3 different chargers. Makes no difference to my phone. What's interesting about AndroTS GPS Test is that after plugging/unplugging, sometimes it'll show as if the GPS chip tries to power back on after the plug/unplug and tries to achieve a lock, it gets as far as 5/5 satellites and then seems like everything powers off again. Of course that happens in about a second or so but that's the only GPS test that's showed all of those states. I'm gonna wait another day or two to see if anyone has an answer, otherwise I'm bringing my phone back in, this is something that should not be happening on a $299+8% tax on $700-800 phone.

Re: Samsung Galaxy Note 3 GPS Issue

@goldendrag0n That is a killer app (https://play.google.com/store/apps/details?id=com.androits.gps.test.free) and yes it shows the GPS chip (upper left corner) powering off when I plug in the device. The fact that my 0.75A charger does not kill it but your 0.7A charger does is insane. 


I'm making a plea to everyone here and everyone that reads this, IF YOU HAVE GPS ISSUES CALL AT&T AND GET A REPLACEMENT. If we get enogh people calling, yelling..., maybe they can make a fix for it.

Re: Samsung Galaxy Note 3 GPS Issue

Mine and my wifes both have this issue. We were riding down south to a frends house and mine lost gps signal and my wifes would never connect. ATT wont do anything. Look at the issues with the wifi dropping also. I think both are are the same chip so its probobly a hardware issue. I 

went and got a LTM Garmin GPS from bestbuy during Black Friday thank god.

Re: Samsung Galaxy Note 3 GPS Issue


I just received my new, wait scratch that, 3rd referbished Note 3 (yes it has MJ5) from FedEx. Just did the OEM 2.1A charger plug/unplug test, GPS icon still there. So I rebooted the phone, then let it get a full lock while on wifi, walked down the street to make it switch to 4G, still good. Still need to test 4G to LTE, but I'll do that later and report back.


Like I said, if you are having GPS issues, call AT&T and get a replacement. If they don't want to replace it, ask for a supervisor. Remeber to be very nice and polite and the supervisor will help you. Let's see how long this one lasts, maybe I'll get luckey this time... Now the "fun" Smiley Frustrated task of reinstalling everything


[UPDATE 1/16/14] - Everything & all my apps are reinstalled. Went out and after testing last night and this morning (4G - LTE and back) multiple times thorugh multiple areas, including making and receiving calls in an LTE area, so far my GPS is working. 


There is something odd, the GPS icon will blink like it is trying to get a lock, but when I check how close the lock is, it is about 3 meters. Not sure if it means anything, but it works (knock on wood)...

Re: Samsung Galaxy Note 3 GPS Issue

I finally managed to find a somewhat fix for my Samsung Note 3 GPS lock problem. The problem seems to be software related, note hardware. After rooting my note 3 and installing a ROM that did not solve the problem, I installed unofficial KitKat ROM,


[Edited to comply with Guidelines]


My GPS now locks every time I power on my Note 3, using the free app: "GPS test", it locks to the satelites just as effective as my Note 1. When I see the lock taking place in GPS test, I open Sygic (the car navigation program I prefer to use) - and this works super. However, if I turn on my phone and do not open the app GPS test straight away, then the lock problem happen again. But every time I restart mye Note 3 (power off, then power on / do a reboot), the unofficial KitKat ROM really do a great job. 


My guess is that the Samsung Note 3 GPS lock problem is partly caused by a "permission conflict", a purely software problem that Samsung can solve making a update.


When the official KitKat update / ROM is launched by Samsung for Note 3, and if the GPS lock problem still is not solved, this will really be a catastrophe or incompetence on behalf of the Samsung team responsible for the Note 3 GPS.    


Take care Smiley Happy

Re: Samsung Galaxy Note 3 GPS Issue

Wow not even 24 hours this time. Plug/un-plug & switching between 4G/LTE it dropps again. I even tried going into safe mode (while powering on the device,. keep hitting the menu button) to disable all of the installed apps, still nothing. 


I know this sound wierd, but I wonder if there is some hidden power save menu for the GPS?


I'm did a factory reset and it started working... I'm only going to install Ingress and Ingress wakelock and see how long this lasts. This should not happen with an $800 device. I think this is the last time I get a Samsung

Re: Samsung Galaxy Note 3 GPS Issue

Add me to the GPS issue.  It looks like I have the issue when you plug and unplug the charger, change the cell phone towers (from LTE to 4G and back), and it also loses the GPS signal when the phone is put in and out of airplane mode.  


I called ATT support and they transferred me to samsung.  After a few diagnostics they said I need to send the phone in/get a replacement.  


Before calling ATT support I reset the phone to factory.  Resetting it fixed the gps issue for one day.  After the reset I could plug/unplug the charger, change cell towers, and put the phone in and out of airport mode without the GPS turning off.  However after one day the GPS issue came back.


After the GPS problem came back, I stopped at the ATT store and tested the two note 3s they had on display and both of them had the GPS issue.  Also while talking to an employee at the store and showing him the problem with the two phones they had on display, he took out his note 3 and it also had the GPS issue.  He never knew he had the problem. 


It also looks like this could mainly be an AT&T problem.  I have checked three verizon and two T Mobile note 3s and none of them have the GPS problem.


I just reset the phone again and the GPS is again working correctly.  Will wait and see.

Re: Samsung Galaxy Note 3 GPS Issue

@james27007 @nicman @TeddySkinner 

Like you guys I have been doing the same thing. After wipe it seems to work fine, and I do suspect it's a software issue. I was actually in the process of writing an update here last night, as I was writing I decided to check it one more time to be absolutely sure I'd gotten rid of the problem when it happened again.

At the time I suspected the Flipboard widget that's preinstalled on our homescreen as that was the last app I started up before it happened. So then I wiped my phone a second time last night to test out Flipboard, but to my dismay the GPS continued to work perfectly even after I had signed in to the widget. Then I suspected GSam as that was the app I set up prior to Flipboard. So I left GSam uninstalled since the wipe last night, everything was still working until a few hours ago. I was going to drop by here and give an update when I thought, okay one last test... then boom we're back to square one.

It has to be some sort of software issue as all 3 of us have noticed, a factory wipe without installing apps/backup restore works but after we install our apps and use it for a day or so it bugs out again. But I can't think of what might be causing it, what app could affect the GPS chip like that? Plugging/unplugging normally has NOTHING to do with the GPS, so why is it causing it to shutdown. And the 4G LE to 4G switch too, it's on a separate radio, so how does it affect GPS? This is beyond annoying but at least we've been able to confirm with a 80-90% probability that it's not a hardware problem.

Re: Samsung Galaxy Note 3 GPS Issue

Also head to this thread on XDA where a few others confirm it's some sort of software problem and flashing to X-Note ROM has solved their issues.


Hopefully the jump to KitKat will fix this issue.

Re: Samsung Galaxy Note 3 GPS Issue

Add another one,owned my note 3 for about 10 days this issue kept occurring swapped it out for another new one same issue yet again. I really don't believe it's a hardware issue definitely seems like something related to when it switches from 4G To LTE and so forth. In any case I hope it gets fixed either by kitkat or some update as for such a high end expensive phone this is unacceptable.

Re: Samsung Galaxy Note 3 GPS Issue

P.S before any AT&T "technical support" mentions factory reset again been down that path also. (P.p.s rarely does that actually fix any issue for any phone beyond a day or two.)
